When you extract your data, put it into a well defined class. For instance, if you were reading in an animals structure, you might have a class that looks like this:

public class Animal
{
  public string Name { get; set; }
}

Create an observable collection that wraps the animals and populate it with your data reader. [Hint - you might want to use my RangeObservableCollection[^] class in place of the ObservableCollection because it's better suited for bulk loading information into without firing off the notification events]. Then, bind this to your DataContext and use WPF databinding to bind the combobox to this. I know this seems to be a lot, but it's not as bad as it sounds and there are plenty of examples on this.

Indeed, I was going to recommend an observable collection; but he said he did not want any databinding.

Come to think of it; why do you not want databinding? Just curious.

Haven't got round to learning databinding yet, just trying a few simple things with basics.

when i tried the solution above i get

Error 1 'BikeMaint.Modules.AccessDB.GetBikesAlreadyStored(BikeMaint.Window1)' is inaccessible due to its protection level G:\Programming\Projects\bikemaint\Window1.xaml.cs 103 18 BikeMaint

?

It means that the method GetBikesAlreadyStored isn't declared as public or internal (assuming it's all in the same assembly) so it can't be accessed by an object outside its class. You've probably got it declared as private or protected (or without a scope identifier at all).

Hello,

Silverlight is using smaller version of CLR which is totally different from .NET CLR. So, the assembly which is complied using Silverlight CLR and the .NET assembly are not binary compatible. That's why you can't reference .NET dll in Silverlight project.

You will need to re-compile your sourcecode with Silverlight CLR if you want to add the reference in Silverlight.

All you need to do is that create Silverlight Class Library and copy all of your code from your project to new Silverlight Class Library project and try to build it again. There are a lot of namespaces that are not supported in Silverlight so that you have to find the workaround for them. Once you can successfully compile the project, you will get the assembly that you can reference in Silverlight.

Hope it helps.

Thanks and Regards,

Hi All,

This is only slightly related to WPF really. I'm currently overhauling my personal web site and I'm including lots of code bits (C# & XAML).

The problem is, I'm having troubles finding decent syntax highlighting stuff that does C# and XAML to an acceptable standard. The site is php/html/javascript so I can't use any nice asp.net stuff ... boo!

Any one have any ideas?

The syntax highlighters I've found so far are ok, but XAML highlighted as XML just doesn't cut it imho ...

Cheers,

Jammer

To be honest, over the last couple of years I've lost track of the number of Syntax Highlighters I've tried and frankly I've not been completely satisfied with any of them ...

XAML is completely unrepresented at the moment as far as I can tell. Frown | :(

Too true. That's why I use screenshots (btw - that's how Josh and Karl do it as well).

I carried on with dp.SyntaxHighlighter in the end. Have just finished the new version of my web site too. I wanted to put my CP articles up and have the code easily accessible for people to cut and paste.

It looks good. I'm playing round with a Silverlight code control as a bit of fun. So far, it's been pretty good fun.

Notepad++ (free) highlights pretty well and you can export in HTML.

Well, really that's just me being anal about it. I just wanna have XAML snippets on my site in the exact format one gets used to viewing it on screen. I actually find code more difficult to read if the highlighting is wrong than with no highlighting at all!

WPF ListView/ItemsControl Drag Drop Adorner

Hi there,

I've found this article by Bea Stollnitz and downloaded the source and converted to vb.net. I believe I have my conversion complete, but one thing is still not working as I've tried to get it and pulled too many hairs out. Hopefully someone can help me spot what I'm missing.

Ok, drag & drop works fine in the converted code, I just don't get the InsertionAdorner working in vb.net, I've setup breakpoints in code and all code is being executed, but for the life of me the InsertionAdorner does not become visible. Even the DrawLine functions are being called!

I'm at a loss and I need this in vb.net, the original C# project works just fine, I just can't find out what I'm missing!

Thanks,
Scott

If you want to convert this to VB.NET, use Reflector to open the exe up in Bea's solution (File > Open... pick the file). Then, expand the various items in DragDropListBox and choose Visual Basic in the language combo. Click Space to see the Disassembler window, and choose each class (e.g. Album) in turn. At the bottom of the Disassembler window is a link "Expand Methods" - click this to see the converted code.
